Review in a different language

Ich bin nicht Deutscher, aber ich spreche Deutsch.

This may be a side effect of merging the international versions of IMDb into the main version. I vaguely remember that an IMDb staff member stated that reviews written in languages other than English will be retained, but that some functionality from the international versions still needs to be incorporated. If I find the post, I will link to it in this thread. It's also possible that I am misremembering this.

One other possibility is that your browser is marking the words wrong. Mozilla Foxfire has a built in spell check feature; it marks all of the words in the first phrase of this post except bin as misspelled.
